Figure 32: (a) Potential vorticity distribution in units of 10- 14 cm- 1 S-l at the Labrador
Sea Water potential vorrticty minimum. Compilation by Talley and McCartney, 1982,
based on data from years 1957-1964. Dots indicate the location of the 1991 VIVALDI
survey. (b) VIVALDI potential vorticity distri bution at the potential vorticity minimum of
the Labrador Sea Water in the eastern North Atlantic expressed in units OflO- 14 cm- 1 S-l.
Location shown in Figure 32a. From Cunningham and Raine, 1995.
